Answers

Answer 1

Answer:

MP =  Rs. 1500

SP =  Rs. 1230

Step-by-step explanation:

Let the Cost Price (CP) be x

Then Market Price (MP):

MP = x+ 20% = 1.2x

Discounted Selling Price (SP):

SP = MP - 18% = 0.82*1.2x = 0.984x

Since the difference between CP and SP is Rs.20:

x - 0.984x = 200.016x = 20x= 20/0.016x = 1250

Then:

MP = 1.2*1250= Rs. 1500

and

SP = 1500*0.82 = Rs. 1230

0.29 rounded? I need this for msth and quick!!

Answers

.3 is that rounded to the nearest tenth

Answer:

0.29 rounded to the nearest ones is 0.

0.29 rounded to the nearest tenths is 0.3

0.29 rounded to the nearest hundredths is 0.29

Step-by-step explanation:

Note that when rounding, you always look at the place value directly next to the one you are rounding. Note that if the digit is 5 or greater, round up; If 4 or less, round down.

Round to the nearest ones:

Look at the place value directly next to the ones (tenths place value). It is a 2. Because 2 is less than 5, round down:

0.29 rounded to the nearest ones is 0.

Round to the nearest tenths:

Look at the place value directly next to the tenths (hundredth place value). It is a 9. Because 9 is greater than 5, round up:

0.29 rounded to the nearest tenths is 0.3

Round to the nearest hundredths:

Look at the place value directly next to the hundredths (thousandths place value). Because there is no number, it is typically signified by a 0 (place holder).

0.29 rounded to the nearest hundredths is 0.29

A delivery person uses a service elevator to bring boxes of books up to an office. The delivery person weighs 160 lb and each box of books weighs 40 lb. The maximum capacity of the elevator is 670 lb. How many boxes of books can the delivery person bring up at one​ time?

Answers

Answer:

Step-by-step explanation:

So if the delivery person weights 160 lbs than we’re going to subtract 670-160=510 next we divide 40 into 510 which is 12.75. Which means that he can bring 12 boxes.

Answer:

12

Step-by-step explanation:

max cap 670lb- delivery person 160lb  weight left 510lb

weight 510lb/each box 40lb number of boxes 12.75lb

each box 40lb times number of boxes 12lb  480lb+160lb 640lb

so your still have 30 lb before max weight of elevator

A store sells three varieties of cheese cheddar, Gouda, and Swiss. Each variety of cheese is available in two different styles shredded or sliced. How many possible outcomes for the variety and style of cheese are there?

Answers

Answer:

6 possible outcomes

Step-by-step explanation:

To solve this problem, we have to make use of the Fundamental Counting Principle formula.

The formula counting principle states that when we are given two or more distinct events, in order to get the total number of possible outcomes, we multiply such events together.

In the above question, we are given two events.

Event 1

3 varieties of cheese: Cheddar, Gouda, and Swiss.

Event 2

2 styles of cheese: Shredded and Sliced

The possible outcomes for the variety and style of cheese = Event 1 × Event 2

= 3 × 2

6 possible outcomes.

These 6 Possible outcomes are listed below:

1) Cheddar cheese , Shredded

2) Cheddar cheese , Sliced

3) Gouda cheese , Shredded

4) Gouda cheese , Sliced

5) Swiss cheese , Shredded

6) Swiss cheese , Sliced

Find the equation of the line below.

Answers

Answer:

y = 2x

Step-by-step explanation:

The equation of a line is y = mx + b

We can plug in values for x and y,:

x = 1, y = 2

2 = m + b  <- equation 1

x = 4 y = 8

8 = 4m + b <- equation 2

We can multiply equation 1 by 4, getting 8 = 4m + 4b.

We can them subtract equation 1 by equation 2, getting 3b = 0.

Therefore, b = 0.

We can use the equation 2 = m + b and find m:

Since b = 0, m = 2.

The equation is then y = 2x.

Only simplify don’t actually solve and if u give me the right answer first I’ll give u the crown

Answers

So, there’s a few problems here.
Firstly, is the w meant to represent the second number as an exponent? because if so, the correct symbol is (^) and it should look like (40^4) and (8^6). Or is the w meant to be a variable and you need to simplify (40*w*4) and (8*w*6).

Secondly, if you did mean you need (40^4) and (8^6) to be simplified, the only way something can be simplified without being solved is if the equation has a variable(letter) in it such as x or y.

To simplify something means combining the terms until there is nothing left you are able to do. So solving the problems would be simplifying them since they have no variables

If you did mean (40^4) and (8^6) to be simplified, the answers would be
40^4= 2,560,000
8^6=262,144

I hope this information was helpful in anyway, I would be happy to help you if you could clarify for me what you want simplified by leaving a comment on this answer

The are of a rectangle is 50m^2 , the length is 100m . Calculate the width

Answers

Answer:

w = 0.5 m

Step-by-step explanation:

A = l × w

50m² = 100m × w

w = 50m²/100m

w = 0.5 m

Answer:

The answer is 0.5 m i.e Width = 0.5 m

Step-by-step explanation:

Given,

Area (A) = [tex]50m^{2}[/tex]

length (l) =100 m

Solve the system of linear equations in two variables by elimination or substitution.
2x + 4y = 4
2x - y=1

Answers

Answer:

x = 0.8    y = 0.6

Step-by-step explanation:

Solve one of the equations for a single variable, I chose the 2nd equation and solved for the variable y and I got y = 2x -1.

Next plug in the value for y into the 1st equation, I got :

2x + 4 ( 2x - 1) = 4

Next solve for x by first distributing the 4 to the (2x-1), this becomes (8x -4) then add like terms and move the -4 to the other side of the equation by addition. I got 10x =8 then I divided 8/10 to solve for x and I got 0.8.

Now plug the value 0.8 in for x in the 2nd equation : 2*(0.8) - y = 1

Then solve for y by subtracting 2*(0.8) or 1.6 from 1 and I got -0.6, lastly divide by -1 to solve for y.
